Issues with computeclass created with resource limit/request.

[sangee2004]

acorn version - v0.10.0-rc2+e32a2709

Steps to reproduce the problem:

1. Try to create a ClusterComputeClassInstance with resource limit/request set to integer values.

kind: ClusterComputeClassInstance
apiVersion: internal.admin.acorn.io/v1
default: true
metadata:
  name: cc1
description: Large compute for linux on arm64
cpuScaler: 0.75
supportedRegions:
 - local
memory:
  default: 20M
  min: 10M
  max: 100M
runtimeClassName: mytestclass
resources:
  limits:
    gpu-vendor.example/example-gpu: 2
    test2: 2
  requests:
    gpu-vendor.example/example-gpu: 1
    test2: 1

2. This fails with following errors:

kubectl apply -f ccnew.yaml           
The ClusterComputeClassInstance "cc1" is invalid: 
* resources.limits.gpu-vendor.example/example-gpu: Invalid value: "integer": resources.limits.gpu-vendor.example/example-gpu in body must be of type string: "integer"
* resources.limits.test2: Invalid value: "integer": resources.limits.test2 in body must be of type string: "integer"
* resources.requests.gpu-vendor.example/example-gpu: Invalid value: "integer": resources.requests.gpu-vendor.example/example-gpu in body must be of type string: "integer"
* resources.requests.test2: Invalid value: "integer": resources.requests.test2 in body must be of type string: "integer"

3. Try to create a ClusterComputeClassInstance with resource limit/request set to string. This succeeds. But app deployment using this computeclass fails with following error

  ✗  ERROR:  App.api.acorn.io "mytest" is invalid: spec.image: Invalid value: "2601fcb549cec80e17651e1eb9163a7dead87dd7ec344e9e569e2a95e6410763": error listing compute classes: quantities must match the regular expression '^([+-]?[0-9.]+)([eEinumkKMGTP]*[-+]?[0-9]*)$'

Same error is also seen when listing computeclass

acorn offerings computeclass 
  ✗  ERROR:  quantities must match the regular expression '^([+-]?[0-9.]+)([eEinumkKMGTP]*[-+]?[0-9]*)$'

Tested with acorn version - v0.10.0-rc2-9-g43dbcbf4+43dbcbf4

1. Able to create a computeclass with resources field containing requests and limits using following yaml :

kind: ClusterComputeClass
apiVersion: admin.acorn.io/v1
default: false
metadata:
  name: cc-res
description: Large compute for linux on arm64
cpuScaler: 0.75
supportedRegions:
 - local
memory:
  default: 20M
  min: 10M
  max: 100M
resources:
  limits:
    gpu-vendor.example/example-gpu: 2
  requests:
    gpu-vendor.example/example-gpu: 2

2. Able to list this computeclass using acorn offerings computeclass and deploy apps using this computeclass.
